Purge-and-trap


Purge-and-trap uses an inert gas to strip VOCs from aqueous samples (such as drinking water or soil samples), before concentrating them onto a cooled focusing trap similar to that used in thermal desorption, followed by desorption onto the GC column.


EST Analytical’s Evolution purge-and-trap concentrator delivers high productivity and reliability, while complying with numerous standard methods (e.g. US EPA Method 8260).
